Stihl air filters.

[mendiplogs]

As far as I know the backplate changed design to accommodate the HD2 filter. Only older saws are different I think. If you have the HD2, that's as good as mr Stihl can do it seems:thumbdown:

 

The foam or felty wrap thingies take a fair bit of power, more noticeably so when milling as you're cutting at max power for much longer then when felling/crosscutting etc. This is why I use tights as a pre-filter as I can swap them as often as I want, paying for a dozen stihl wraps to remedy a problem that should have been designed out of these saws is not on imo:thumbdown:

 

HD2 after three tankfulls of crosscutting (I change it continuously when milling..)

Hi mate I use the felt air filter around the HD FILET thanks Jon

Kind of difficult when the opposition has already patented the only practical filtration system

Really? Please elaborate as I'm interested.

 

What with Stihl having to rent 2-mix (X-torque) off Husky (if that's true?) then they may as well give up!

 

Seriously though, I love Stihl. They just keep going.

Air injection is the way forward! I believe stihl now use some thing like it on new saws but the 66 is an old design.

Correction, stihl rent 2-mix, m-tronic and what ever they call the air injection, in return, husky rents elastostart... And gets zama carbs at a cheap rate, which they sell back to stihl at a premium. Stihl only started renting husky tech after the buy-out fell through in 2006. Husky still have the edge in tech, and I imagine they will for a good while, unless stihl drop the 4-mix and go more with the fuel injection system.

 

And yes, it is true, you may only use something that somebody else has patented if they give permission, as they would definitely sue each other if they didn't get royalties for their creations

The air injection is the filtration method you mention earlier?

 

Elastostart for 2-mix hardly seems a fair swap, I presume there's extra money that changes hands towards Husky.

Yes, the reference was to air injection, there is no other practical way to pre-filter the intake air without loosing volume of air intake.

And yes husky takes more off stihl than the opposite, or at least enough to pay researchers to come up with revboost, crank stuffers and carburettors smart enough to know what you had for breakfast

Cheers for the advice guys. Out of interest what sort of air filters do the huskys run? anyone got any pics/or had any issues with them?

The big difference isn't in the filter, rather what happens before that. On Husky saws the air spun round by the flywheel fans gets cut in half by a plastic bit. The outside will have most of the sawdust in it due to the centrifugal force. The inside (much cleaner air) gets fed to the filter.
